METHOD F SEALING BOTTLES.

v To'all whom "it may concern:

`for so fastening a cap over the mouth and about the neck of a milk-bottle, j elly-glass or jar, perfume-bottle, and the like, for sealing it, as to avoid the use of any form of stopper to enter the mouth, and to facilitate thesealing operation while rendering the removal -of the cap easy and convenient.

Referring to the accompanyin drawings-Fiofure lis a plan view of one of various fbrms of machines suitable for fas tening the metal band about the skirtortion of a cap for sealing therewith a ottle, or the like, in accordance with our invention. Fig. 2 is a perspective view of a suitable form of cap to be used for the sealing-purpose, and Fig. 3 is a sim1larl view of the ca with a metal band encircling it, ready to e applied to a bottle to'be sealed. Fig. 4 is a broken perspective View showing a neck of a milk-bottle sealed inY accordance with our invention and employing for the purpose one of various usable forms of metal bands; andFig. 5 is a similar view ofthe same showing a wire forming themetal cap-fastening band after being crimped by squeezing it. Fig. 6 is a plan view of a tapered strip of sheet metal suitable for forming a tubular metal fasteningband like that in Fig. 4, and Fig. 7 is a similar view of the same slightly modified to produce a stop in the iinished band for the purpose herelnafter explained. FiO. 8 is l a plan view of the tubular band ma e from the stri of Fig. 6,r and Fig. 9 is a similar view o such a band made from the strip of Fig. 7. Fig. 10 is a plan View of the band of Fig. 9 showing, somewhat exaggerated, the crimped condition to which it 1s reduced by fastening it about the skirt of a sealing-cap on a bottle, as in Fig. 5; Fig. 11n is an endless fastening-band of mere wire, and Fig. 12 shows, also somewhat ex aggerated, the crimped condition of the same produced byfastening it in its operative position; Fig. 13 is a view, like that presented in Fi 11, of an endless fastening-band forme of sheet-metal, and Fig. 14 shows Specification of Letters Patent.

t the band of Fig. 13 in the likewise exaggerated crimped'condition to which it is reduced by fastening it about the skirt-portion of a bottle-sealing cap.

The cap 15 shown may be best formed of comparatively heavy paper, though any other suitable flexible material may be eln- I, ployed; and it is preferably reduced to a j permanent cap-form ready for ap lication j to seat over and cover the mouth o a bottle l and encircle the neck, represented at 17 i (Figs. l1 and 5), though it may be a flat plcce `of the material adapted to be folded j into cap-shape over the bottle-mouth and about its neck-portion, either way providing the skirt-portion 16 of the cap, with the advantage in the prepared cap of enabling it to be provided about the free edge of the skirt-portion with a seating-fiange 18 for the fastening-band hereinafter described.

lVith a formed cap applied to a bottle j and encircled by a band of flexible metal j and ot any suitable type, including any of the types illustrated, the band is squeezed or compressed in place to tighten it about i the bottle-neck and fasten about the same the skirt-portion of the cap, thus sealing the bottle. This operation may be readily performed by inserting the bottle-neck into and operating against it a suitable machine, such as that illustrated in Fig. 1 and denoted, as a whole, by the reference-character 20. It involves an annular table 21 on which is rotatably confined a ring 22 provided with an operating-handle 23 and containing, at equal intervals apart, similar oblique slots 24; and from a point adjacent to the inner end of each slot a rigid bearing 25 projects radially from the inner edge ot the annular bed toward its center. In each bearing is reciprocably supported a similar plunger 2G provided near its outer end with a stud 27 engaging the adjacent cani-slot 24 and terminating at. its inner end in a head 28 presenting an arc-shaped face. These heads form about the center of the machine a sectional annulus through. which a bottle-neck may be inserted, as by introducing it into the machine from underneath the table 21. vWith a bottle-neck in the aforesaid annulus and equipped with a band-encircled cap 15, by

' in place. as hereinafter described; and turning the 'handle in the opposite direction effects Withdrawal of the plungers and release of the bottle.

As Will be understood, dealers in the material contained in the bottles will be equipped With machines, such as the machine 20, for sealing them and also, by preference, with supplies of the caps 15 which are adapted, by their flaring shape, to be shipped to them in nested condition with a band 19 about each, bearing against the flange 18, ready for applying the cap in place and subjecting the band to the action of the machine. A desirable type of the band is that shown in Fig. 8, AWhich is produced from a sheet-metal strip 191 (Fig. 6) by bending it lengthwise upon itself into a tapering tube and reducing this tube into circular form with the narrower end telescoping the Wider end. In subjecting this band `to the action of the machine 20, the encircling plungers compress it about the skirt of the sealingcap to tighten it against the latter,` thereby forcing and Wedging the narrower end into the Wider end of the annular tube. This same type of band may be produced in the form represented in Fig. 9 from the tapering sheet-metal strip 192 of Fig. 7, which differs from that of Fig. 6 in containing an offset in its narrower end-portion. This ottset presents, in the band of Fig. 9, a shoulder 193 forming a stop which prevents the action of the machine from driving the narrower into the Wider end of the tubular band; so that when the plungers 26 are caused to exert their pressure against this band, Which should be set in the machine to bring the telescoping sections into the path of one of the plunger-heads, the exertion by the heads of the circumferential compression on the band will crimp it into the shape or approximately the shape illustrated in Fig. 10, one of the crimps being formed at the telescoping joint to clench it, as represented at 19". The bands of Figs. 11 and 13 are endless, the irst-named being formed of non-resilient Wire of round cross-section and the other ot sheet-metal. Obviously, being endless, as is, practically, the band of Fig. 9, the compression-action upon them of the plungers in the machine will crimp them, as represented by the Wire band of Fig. 12 and by the vsheet-metal band ot Fig. 14. ln every instance, however, the band is tightened b`y squeezing it about the cap-skirt to fasten the cap into sealing condition upon the bottle. This mode of asteningi the cap in place renders it readily removable for emptying the contents ot the bottle, since to free it all that is required is to torce .the

oaxaca band, as With a fork or anysuitable implement, applied to any point thereon, past the flanged edge of the cap, thereby permitting the latter to be readily pulled or torn otf'; or, if desired, the crown-portion of the cap may be cut away, thus opening the bottle Withoutdisturbing the band.

Our improvement is peculiarly etfective in its purpose in connection with bottles with circumferentially -beaded mouths, like the representations in Figs. t and 5,' since, in compressing the band in. the manner described, it tends to stretch the cap-skirtabout the bead and thus draw the cap tautly over ing` the bottle because of the closeness and by compressing the band as described.

We reserve the article produced by, our method ot sealing for the subject ot'a future application for Letters Patent.

1What We claim as nevi7 and desire to secure by Letters Patent is like, which consists in seating a flexible cap over the mouth of the bottle With'the skirtportion of the cap extending about the neck ont the bottle, applying a ring of flexiblemetal about said skirt-portion, and diametrically contracting said ring by circumferential pressure simultaneously applied atdifover the mouth of the bottle With the skirtof the bottle, applying a ring of flexiblemetal about said skirt-portion and diametrically contracting said ring by circumferential pressure simultaneously applied at dit'- ferent points thereof, whereby said ring and the skirt-portion of the cap are crimped together at such points ot' pressure and the cap 1s astened in place.
